Samuel Lard/Laird Giles Co, TN 1830 census

On the 1830 Giles Co, TN census, there are a few Lard/Laird familys...I know that one of them was John Laird of Ireland who married a Maria Tuttle...he has a brother Mathew who went to Indiana...then there was a Samuel Lard listed. This is the man I would like to find out more information on. I don't have a census listing of him afte the 1830. Would anyone have any information on this line. The census states 3 sons under age 15 and 2 daughters 5/10 and 10/15. The 10/15 age female , I am hoping is my Elizabeth Laird who married Samuel Moyers. I have a lot of info on that side of the family , but literally nothing on Elizabeth , and most of the Moyers researchers have no clue as to whom she belonged to or her family ties. Any help, suggestions, or info is most appreciated.
